sHovEL ATTACHMENT. A

Application med August 7, i922. seriai No. 580,126,

To all who/m, t may concern.:

Be it known that I, THOMAS NEWMAN, a citizen of the United States, residing at Omaha, in the county of Douglas and State of Nebraska, have invented certain new and useful Improvements in a Shovel Attachment, of which the following is a specification.

This invention relates to an attachment useful in connection with manually operated implements requiring swinging and lifting movements, and of particular advantage when applied to scoop shovels. Oneof the objects of the invention is to provide a pivot allyl mounted lifting-bar forthe handlev of a shovel or. similar implement so that an operator when using it may assume a less stooping lposition than ordinary. Another object is to provide resilient vmeans normally causing the bar to move rearwardly toward the handle, for convenience in operation. p. Still another object is to provide a pivotal `mounting for the bar near the load tO-be lifted and nearer to the blade or bowl of the implement than that part of the handle usually grasped by the hand of an operator, to facilitate oper-t ation. .The invention includes a lifting-bar provided with a hand-piece and having divergent arms, together with certain adjusta-v ble features found to be of advantageand fully explainedl herein. Another, object of the invention is to provide an attachment which will consist of 'few and simple parts so that it maybe manufactured economically, y

will be durable, and may be conveniently applied to shovels or similar implements.A

In the accompanyingr drawing which illustrates the'invention, Fig.4 l is a sectional view through vthe handle of an implement and arms of a lifting-bar to clearly show the mounting of a segmental spring-support or loop. Fig. 2 is a side view of a scoop shovel provided with the attachment, the spring being retracted and the lifting-bar disposed in a normal position'. Fig. B is a side view of the same, the lifting-bar being swung upwardly and the spring being contracted. Fig. 4 is a plan view showing a part of a handle with the device mounted thereon.

Referring now to the drawing for a more particular description, numeral 5 indicates the handle of a scoop shovel, and in order that operation may be facilitated, I provide an attachment consisting, in part, of a lifting-bar 6 which includes a pair of divergent arms 7 having a pivotal mounting 8 upon the l shank 9, closely adjacent to the bowl Vor blade 10 of the shovel, said bar 6 having` aholder elementv llat its free end,'andbeing provided at longitudinal intervalswith'numerous apertures 12 for use in removably connecting the arms therewith, by means of keepers x As thus described, an operator may grasp the holder element 11 of they bar and the l' l liand-piece 13 of the handle 5 for operating' the shovel, and the work will be more/conf venient and less laborious thany usual, 'since the hands and arms .of an operator may 'rei' main further from the ground, and the eX- treme 'stooping orleaning positionoveithe work, usually experienced, will not be required, the lifting-bar together withitsyar'ms,

having'a swinging movementfrom thepivotI 8; and since the pivotal mounting 8 is on y l adapted to engage in any 0f the "apertures` 12 which may be selected, after the'arms'. 7

have been moved longitudinally of the'bar: 6.

' It will be noted that the holder 11 projects outwardly of the side of theLhandlej, this' being a matter of convenience, and-by refer-y ringto Fig. 4C it will beseen 4that the *device i' maybe' adjusted for the use of a right handed or cleft-handedoperator, since the bar 6 is rectilinear and may, bef," reversed, the

and the bar `swung a half circlel so ythat mem! ber 11 willproject from the side -of the handle 5, opposite to that shown in Fig. 11;'

The parts thus described may 'be iisedl'to keepers m being removed for this 'purpose' advantage ini many instances whenfvapplied to forks,vshovels or'fsimilar:implements,-but i for use Vwhen heavy material 'is to be moved, resilient means `are employed, and now to described, said means voperating toresista/ to swing toward the handle after ithas beenforcibly'swung outwardly therefrom. F/ach' arm 7 ofthe lifting-bar '6 4is provided, adjacent to its pivotal mounting'S,-

with a staple-plate 14. vAt 15 is indicated abearing-plate, best shown in Fig. 1, said plate, near its ends, being provided with apertures c. and adapted to engage the lower` iOO swinging movement of the bar v6 outwardly from the handle 5,l and normally `causingit side of the-handle 5. At lis indicated a. bearing-plate having apertures and adapted to engage the upper side of said handle and thearnis 7.

Numeral 17 indicates a curved rod or loop upon Which is mounted a spiral spring c, the arms orn said loop being of segmental form and each having end-portion traversing a staple-plate of lan arm 7, an aperture a. and an aperture of the respective bearing-plates l5 andv I6, nuts i8 beting threaded onthe. ends of the loop. Y

Since the arms ofthe loop are of segmental form the loop will not be obtrusive in use, but normally, will lie closely adjacent to and may engage the rear part of the shovel, as shown, in Fig. 2, and since the curved armsof the loop are eqnidistant from the pivotal mounting 8 off' the arms7 of the lifting-bar, they Will not cause appreciable friction While moving through the sta-ples and apertures ot the bearing-plates.

It is obvious that an operator, by Vuse ot the hand-holds 1,1 and, 13, may lift a load Without excessive stooping or bending. Dnring this operation the lifting-bar will graduallyswing outwardly from the handle 5 aga-inst the forcefof the spring c, the plate l5 being pressed by the, spring against the handle 5.,; andatter the load is discharged from the shovel,A the barV 7 'Willswing toivard the handle by force of the spring, ready 'forr another operation.

. While I havedescribedk details of constructionI donot/vvish to be understood, as limit- 1 g mysel in this respect, andv changes in form,si,ze, proportion and minor details may be made as pund tobe of advantage, said changes being Within thescope of theinvention` as claimed..

I claim as invention,-

1. In an attachment for an implement havingV ay hhandle, a,l lifting-bar pivotally mpunted, on said handle, and. resilient means connected, With thelit'ting-bar and handle and lactuated by a swinging movement of saidv bar. for resistingv a movement ot the bar in one direction.

2. In an attachment for. an. implement having a. handle, a pair of armspivotally mounted on' opposed sides ofthe handle and extending convergingly therefrom, a bar adapted to be swungk transversely approximately a halt circleto be4 disposed between said arms inthe plane of the handle, a. holder-element disposed transversely of. and
